concerned withfeed' means for wringers ofv the typementioned, and may beregarded as an nnprovement o'verthe structure disclosed in my prior U.SPatent No. 1,683,352, dated September 4,1928 and filedsby me'onDecember 15, 1927, under Serial'No'. 240,089. In

the aforesaid patented structure,a feeding element having the form of atonguebar is movable from a normalv retracted or loading position towardthe squeeze rollers of the;

aring-er in presentingfthe leading. margin of the material to be wrung,after] having.

been laid over said bar, before entrant blght between thesq-ueezerollersi Inc1den- -tal to feeding, a cooperating:member acts to checkrearward movement of the material on. the bar to insure its vbeingnippedbyth'e.

"I hearings in its vertical end portions, to ro-i 'tatablysupport therubber covered squeeze: I

squeeze rollers.

Amongst the objects-of-my presentinven tion are to provide not only.forposltlonalad justm'ent of the feed bar vertically relative to thelevel of the squeeze rollers, but to enable Ilateral adjustment thereofinto true alignment and-parallelism fwithsaid rollbar; to insurerpositiveengagement of. the

material on the bar by the cooperating! checkmember; and to enable saidcheck v member to be'moved and held out oftheway J when-it is notneeded' In addition to the foregoing, I 'aim to secure the advantagesaccruing tosiinplified construction andarrangement of the parts involvedin feeding the material to the-squeeze" V rollers of thewringer.

Still other obje'ctsand attendantladvam.

tages will be apparent from'thedetailed description which follows whentaken incon; nection with the attached drawings, wherein Fig- I is afrontelevationof a p'oweri wringer convenientlyembodying-my invena tion.Fig. 11' is a fragmentaryend elevation ofthe wringer viewed from theright of Fig. III'is plan section, taken as indie cated by the arrowsIIIIII in Figs. I and II, with the upper squeeze roller removed.

Fig. VII is an exploded view showing,' inperspective, the variousrelatively adjustable I parts which together constitute one .ofithe endmountings for the feed bar.

The wringer herein illustrated is, generally v speakmg tandard :in"construction, 'i. e., it embodies a yoke-like frame 10 with suitablerollers 11,- 12,;and enclosing gearing? to drive between these ismounted an auxiliary drain.

chute 15 which centrally pivoted at 16 ,s0 as'to be tiltable forcooperation with either of the fixed chutes 13', 14' as required foreither forward or reverse operationof the wringer. A bracket partlyshownat 17, in Figs. I and III, serves to support the wringer after themannerofa cantilever horizontally over the receptacle of the washingmachine, said brack'et' being hollow for the passage of the drivingconnections (not shown) -t o the squeeze roller's 12; 1 In standardwringers of the kind brieflydescribed, mechanism is provided to enablereverse operation of the. squeeze rollers11,.12, but since such'meclr"an smis not pertinent 1n thepresent connec-..

tion, ashowing thereof has from the drawings.

The feeding 111 also been omitted from the substantiallyhorizontalloading poeans herein featured comprises a, bar 18with a tongue-likeforward edge 18a, saidv bar-being swingable, upward II, to the uprightactive position, indicated in full lines in Figs. II and III, inpresenting the material M which is to be wrung to the squeeze rollers11, 12. As shown, the bar 18 affords a longitudinal hollow foraccommodation of an auxiliary feed roll 19, and at opposite ends hasside arms 20, with integrally formed pivot trunnions 21, as well as withlaterally projecting manipulating handles 22. Hollowed out transverseguard portions 23 at the ends of the feed bar 18, immediately inward ofthe side arms 20, serve to control flow of the liberated or wrung-outwater inciden tal to passage of the material M between the squeezerollers 11, 12 in a manner more fully explained later. From Figs. II andIV, it will be observed that the pivot trunnions 21, are engaged withinopen top notches 24 of a pair'of-bearing pieces 25, which have pivotalsupport onscrew uds 26, Fig. VII, respec tively let into brackets 27,the latter being secured to the frame of the wringer at one side.Dislodgement of the trunnions 21, prevented by gravity keepers 28, whichare supported for free swinging movement on studs 29, taking into thebearing pieces 25. As a consequence of such pivoting, the bearing pieces25 can be adjusted laterally relative to the brackets 27, for thepurpose of securing true alignmentand parallelism of thefeedbar 18relative to the squeeze rollers 11, 12 horizontally, the adjustmentbeing fixable by means of clamp screws 30, that pass through arcuatcslots 31 in said bearing 7 pieces 25 and engage in lugs 32 of thebrackets 27. Upward movement of the feed bar 18 is limited by stops inthe form of screw studs 33, adjustable in the brackets 27. Set screws 34prevent loosening of the stops 33 after the desired adjustment issecured. As shown in Fig. VII the brackets 27 have vertical slots 35, 36at the top and bottom for passage of securing screws 37, 38, thedescribed arrangement permitting up and down adjustment of the feed bar18 for proper lcve1- ling in relation to the squeeze rollers 11, 12..

In order to enable transposal of the feed bar 18, a pair of brackets 27ais provided at the opposite sideof the wringer frame, the said bracketsbeing identical, both as regards construction and appendages, to thebrackets 27 previously described: and, in order to avoid confusion, allcorresponding parts shown at the right-hand of Figs. II, IV, as well asthe upper half of Fig. III, are distinguished by a primed a. To removethe feed bar 18 for the purpose mentioned, the gravity keepers 28 aresimply swung inwards to clear the trunnions 21 whereupon the latter maybe readily withdrawn from the open top bearings 24. On the other hand,in attaching the feed bar 18, thekeepers 28 will obviously yield todeflection-incidental to placement of the trun- M nions 21 into thenotched bearings 24.

To prevent rearward slippage of the material M on the bar 18 incidentalto feeding, I provide the check member designated by the numeral 39.This check member 39 is .hung in free suspension from a supportingelement 40 having the form of a yoke with side arms 41, pivoted at 42,to the brackets 27. As shown in Figs. I and III the rounded centralportion of the supporting element 40 is engaged by suspension ears ofthe check member 39. These ears 45 are preferably fashioned from stoutwire (see Fig. VI) the ends of the Wire being bent laterally as at 46for force fitment into receiving openings 47 in the thickened endportions 48 of the check member 39. Endwise movement of the mem- 39 isprevented through engagement within a note 1 49 extendingcircumferentially about its rounded upper edge portion, of a centralcollar 50 on the supporting element 40. The described constructionfacilitates ready assembling of the parts, the procedure being asfollows: the check member 39 is brought up so that its notch 49registers with the collar 50 of the supporting element 40 and the wirecars 45, after having previously been placed on said supporting element,forced into the apertures 47. As shown in Figs. I, III and VI, the freeedge of the check member 39 is serrated as at 51 to more effectivelyengage the material M on the feed bar 18. When active, the check member39 rests in an inclined position on the feed bar 18 as shown in Figs. IIand IV, the supporting element 40 being at this time sustainedhorizontally through engagement of its side arms 41 with shoulders 52 onthe brackets 27. For the purpose of holding it in raised position out ofthe way, when it is not needed, the check member 39 is provided with anaperture 53 engageable with a projection 54' on the wringer frame 10.For convenience, the Wringer is equipped with a duplicate check member39a at the opposite side (Figs. II and IV) for cooperation with the feedbar 18 when the latter is transferred to that side of the wringer, saidcheck member 39a being shown in the raised inactive position.

In the use of my invention, a margin of the material M to be Wrungislaid over the feed bar 18 when the latter is in the lowered ordot-and-dash line position of Fig. II. The feed bar 18 is then graspedby the manipulating handles 22 and raised to the full line position ofFigs. II, III and IV, the check member 39 being'incidentally encounteredand thereby caused to assume the angular position shown in Figs. II andIV. Immediately upon grippage of the lapping portion of the material Mbetwen the auxiliary feed roll 19 and. the lower squeeze roll 12, it isautomatically fed forward and rolled into the entrant bight between thetwo cooperating squeeze rollers 11, 12, this being made possible throughthe holding action of the check member 39. As the material passesthrough the squeeze rollers 11, the re squeeze rollers,

' 1 margin of the material a 7 members having rollers 11, 12 formaintenance for diverting the released. water so that it is directedback into the cooperative action between these parts with assurance ofpositive feeding; the provisions tub of the washing machine; and'the provisions promoting action of the material checking member 39 aswell asfacilitating assembling of its parts. 1
